I did a normal daily backup before installing SP2 and I got a hardware compresson ratio of 1.27:1 with an HP LTO960 drive (400GB/800GB comp). My backup of 482GB fit with 36GB to spare. After installing SP2, my hardware compression ratio has dropped to 1.02:1 and now I only fit the first 425GB on the tape before it asks for a second tape. Does anyone know what would cause this? I am using the built in hardware compression on the HP drive. I am trying a backup now with "software" compression to see if that helps.

I tried software compression and it fit on the tape but with 11.3G remaining instead of 36.1G remaining with hardware compression (before sp2). It does not tell you the compression ratio, but calculates out to about 1.18:1.
I just downloaded and installed BE 12.5 (got the email this morning by some coincidence) so I am trying that out now (with hardware compression) to see if that works.
